Description
B&R X20AT4222 4-Channel Pt100 Pt1000 Temperature Module

The B&R X20AT4222 measures four Pt100 or Pt1000 resistance temperature sensors. Sensor type can be configured separately for each channel, while the module connection mode is selected as either 2-wire or 3-wire.

In addition to linearized temperature values, the module can provide direct resistance measurements. It is intended for RTD applications and differs fundamentally from X20AT6402, which is designed for thermocouples and much higher temperature ranges.

Key Features

  • Four RTD temperature inputs
  • Pt100 and Pt1000 support
  • -200 to 850°C measuring range
  • 0.1°C temperature resolution
  • Direct resistance measurement
  • Configurable input filtering

Typical Applications

  • Plastic processing machines
  • Heating and cooling systems
  • Process tanks
  • Bearing temperature monitoring
  • Industrial ovens using RTD sensors

FAQ

Q: Can Pt100 and Pt1000 sensors be used on the same module?

A: Yes. Sensor type is configurable per channel.

Q: Can the module use 2-wire and 3-wire sensors simultaneously?

A: The sensor type is configurable per channel, but the 2-wire or 3-wire connection mode is configured for the module.

Q: Is X20AT4222 suitable for thermocouples?

A: No. X20AT4222 is intended for Pt100 and Pt1000 sensors. X20AT6402 supports thermocouple types J, K, N, S, B and R.
